Schedule is a tool that helps project team achieve project timely delivery objectives. For construction projects, it is common practice that a contractor is brought onboard. In this arrangement the Contract between the owner/employer and contractor becomes the pivotal tool that sets out obligation of either party, which includes the obligation of timely delivery of information, work front, and completed works. While Schedule remains the tool that help projects to achieve timely delivery objective, however, in the employer-contractor-contract setting, the role of the Schedule as a tool broadens from merely time control to the areas like delay analysis, cost and time claim, internal and external communication.
In this scenario failure by a party to achieve milestone or to complete an activity, as required in Schedule, may have a contractual implication, which may result into claims and disputes. Therefore, it is mandatory that the Schedule must incorporate and confirms to the obligations set in the contract. Reading and understanding contract requirements are, therefore, the first step towards schedule preparation. Contractor's Planner/Scheduler requires a certain degree of skill and knowledge to read the contract, and skim relevant information and obligations to incorporate in the Schedule. Same is valid for the owner (or his representative) scheduler at the time of review/approval of the Schedule.
